| Abstract

This study introduces the assessment and prevention methods of explosion and fire risks in workplaces stated in Turkey's national legislation and TSE standards, then applies these methods into fictive chemical facilities. All possible emission points on the tanks, silos or other work equipment that a flammable substance might be released from, should be examined and classified by specific methods and necessary precautions should be taken. As a result of the assessments of the solvent tank and solvent pump in our fictive facility, it has been concluded that tank interior can be classified as Zone 0 explosive atmosphere and various explosive atmosphere assessments can be made for the pump by various engineering approaches. It has also been shown that as a result of the assessment of polymer dust feed hopper, hopper interior can be classified as Zone 20 explosive atmosphere and the distance of the explosive atmosphere that can occur around the hopper can be predicted based on qualitative methods given in the relevant standard. Influence of different cross-sectional area assumptions for a leakage have been assessed on a fictive hydrogen cylinder and as a result it has been shown that assumption have a great impact on both the class and extent of the hazardous area classification. As a result of the assessment of a natural gas valve, hazardous areas around natural gas pipelines with 400 mbar or lower pressure will generally have a negligible extent. The categories and other characteristics of the equipment that can be used within these classified hazardous areas have been identified, and precautions that can be taken against explosion and fire risks in these areas have been summarized. As a result, it was emphasized that accredited laboratories for carrying out standard tests on combustible powders and experimental data for tanks, pumps, solvents etc. which are frequently encountered in the chemical industry are needed in Turkey.
